Description

Technical Field

[0001] The utility model relates to the technical field of concrete special-shaped pipe piles, in particular to a composite reinforced prestressed concrete special-shaped pipe pile. Background Art

[0002] Concrete piles are made of concrete (including ordinary reinforced concrete and prestressed concrete). They have the advantages of saving wood and steel, being durable and inexpensive. They have been widely used in the foundation engineering of hydraulic structures, industrial buildings, civil buildings and bridges. They are also often used for anti-skid or isolation of slope and foundation pit support. Concrete special-shaped pipe piles are a kind of concrete piles. When using concrete special-shaped pipe piles, a pressure device is required to impact them into the soil, and they need to have good strength for use. However, the existing concrete special-shaped pipe piles have low strength for use and are prone to cracking when impacted by the outside world. Therefore, we propose a composite reinforced prestressed concrete special-shaped pipe pile. Summary of the invention

[0003] The utility model aims to provide a composite reinforced prestressed concrete special-shaped pipe pile to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a composite reinforced prestressed concrete special-shaped pipe pile, comprising a concrete special-shaped pipe pile body, the concrete special-shaped pipe pile body comprising a concrete pile, end plates are arranged on both sides of the concrete pile, two groups of end plates are arranged on the side walls away from each other, and four groups of prestressed steel bar hoops are arranged, the outer wall of the concrete pile is provided with multiple groups of convex ribs, six groups of second reinforcing ribs are arranged transversely on the inner wall of the concrete pile, the six groups of second reinforcing ribs are connected with first reinforcing ribs in pairs, the inner walls of the multiple groups of convex ribs are provided with fourth reinforcing ribs, the inner walls of the fourth reinforcing ribs are provided with six groups of third reinforcing ribs, and one ends of the six groups of third reinforcing ribs are respectively connected to the outer walls of the six groups of second reinforcing ribs.

[0005] Furthermore, six groups of the second reinforcing bars are distributed in a circular array inside the concrete pile.

[0006] Furthermore, the first reinforcing rib is arranged in the form of an arc-shaped pile.

[0007] Furthermore, the six groups of the third reinforcing ribs are distributed in a circular array on the inner wall of the fourth reinforcing rib.

[0008] Furthermore, the fourth reinforcing rib is arranged in a ring shape.

[0009] Furthermore, the four groups of prestressed steel bar hoops are distributed in a circular array on the right side wall of the end plate.

[0010] Compared with the prior art, the beneficial effect of the utility model is that the utility model can improve the service strength of the overall concrete special-shaped pipe pile body under the cooperation of the first reinforcement rib, the second reinforcement rib, the third reinforcement rib and the fourth reinforcement rib, so that no cracking will occur when impacted by an external extrusion device, thereby improving the service strength of the concrete special-shaped pipe pile body.
